I'm just testing svn+patch6. A few comments:

The playback causes 90-100% CPU load on my debian64 (AMD64-3000+,
DVB-t Germany) :-O

I had to kill my frontend to exit while it was playing at a higher speed ;)

Rewinding is sort of difficult on LiveTV, it sometimes takes several
seconds to jump back or forward. FE output:
